We just finished a big presentation at the Dutch Microsoft office about the upcomming SharePoint Portal Server 2003 based on the Beta 1. A lot of people were impressed by the new capabilities. In my opinion it is really a step forward in portal software... great collaboration features, everything .NET based, full object model and webservices for development. In the introduction by Microsoft was announced that today (March 10, 2003) the public beta becomes available. After the presentation I directly started the download of the public beta (Beta 2) and I am currently waiting for the download to finish. I can now start writing about it, so there will be more to come at this place in the near future!
